In the global machine tool manufacturing and metal processing fields, composite processing technology is being continuously developed and applied with its powerful processing capabilities. The so-called composite processing technology is to complete the machining requirements of turning, milling, drilling, boring, tapping, reaming, reaming, etc. on one piece of equipment. The most outstanding advantage of the multi-tasking machine tool is that the production cycle of the workpiece can be greatly shortened. Improve the machining accuracy of the workpiece. In order to realize the processing of complex-shaped workpieces, it is possible to complete the processing of multiple processes and multiple types of work on one machine. Such machines are called composite machining machines. That is to say, machining of completely different properties can be realized on a compound machine tool. The range of functions of composite machining machines varies with the times. For a time, the machining center was once called a composite machining machine. However, the general machining center cannot exceed a certain range of machining. Today's multi-tasking machines are not the same as multi-tasking machines at the time, and they are fundamentally different. Modern compound machining machines are further developed, such as milling functions with rotary tools on the turning center, turning functions in the machining center, and recent intensive machining methods such as laser machining and machining. The composite, etc., further enhance the degree of machine tool compounding. The history of the development of composite machining machines In 1845, Ding Fitch invented the turret lathe. In 1911, Greenley Company of the United States developed the first combined machine tool for automotive parts processing. In 1952, the three-axis CNC milling machine was successfully developed. In 1958, KT Company of the United States developed a machining center with an automatic tool exchange device, which strongly promoted the development of processing methods concentrated in the process. Composite processing and its manufacturing equipment have been around for more than a hundred years, but the real application has been widely seen in the 1980s, after CNC technology and CNC machine tools became the mainstream of manufacturing technology. In the mid-to-late 1980s, with the improvement of the function and structure of the machining center, the superiority of the centralized CNC machine tools in this process was revealed, and the turning center, the grinding center, etc. began to appear, so that the composite machining was expanded and not limited to é•—, milling and other processes. In the late 1990s, the turning and milling center, the milling center, the grinding center, etc. were further developed. In recent years, a composite machine tool combining special processing methods such as laser, electric spark and ultrasonic with cutting and grinding methods has emerged to enable composite processing. Technology has become a new hotspot for the development of machine tool structures and manufacturing processes. Classification of composite machining machines Turning-oriented The turning machine based on turning is a turning compound center. The turning compounding center is a lathe-based processing machine. In addition to the turning tools, the tool holder is equipped with a rotary tool that can be milled to machine grooves and planes on circular workpieces and rod-shaped workpieces. Such a multi-tasking machine often makes two spindles for holding a workpiece, and can perform the same processing on two workpieces at the same time, or can perform processing on the clamping portion by alternately clamping on the two spindles. At present, the machining of two or more workpieces accounts for the majority of the turning operations. For efficient and high-precision machining of these workpieces, there are three technologies: Centralization of internal and external processing: One-time/2-time processing machine with various functions of machining (outer surface) and secondary machining (inner surface) in the machine. Machining of the machine: In addition to turning, the machine is equipped with a machining machine with various functions such as milling and grinding. Intelligent: The unit processing machine with the latest monitoring technology such as storage, transportation, processing integration, workpiece identification, workpiece clamping control, adaptive control, information network. This kind of compound machine tool has TRAUB TNX65 multi-function CNC turning center of Germany INDEX company, with double spindle and 4 turrets, the second spindle can be used for Y-axis movement; TWIN65 twin-spindle turning center of Germany DMG Company has one turn The tower tool holder can realize 6-face machining, and the second spindle can be moved laterally. Milling-oriented Multi-axis machining center Five-axis control, in addition to X, Y, Z three-axis control, in order to adapt to the change of tool posture, the five-axis processing machine can be rotated to a specific angular position and positioned. There are two ways to use the five-axis machining machine: 1. Indexing the rotary axis to tilt the workpiece relative to the tool, and performing three-axis control processing in this state. 2 At the same time, all the control axes are continuously moved, that is, five-axis linkage, and the workpiece having an outer curved surface shape such as an impeller can be processed. The five-axis linkage processing machine is characterized by the ability to avoid machining conditions where the cutting speed becomes zero; it is possible to use a tool with a short extension length; it is possible to machine a workpiece with an extended surface shape in one setup. Six-axis control, multi-axis control milling machine can not simulate complex shape workpiece processing, and composite machining can. For example, for the machining of workpieces with a tapered shape and a square-shaped groove, it is impossible to complete the machining without changing the machining work, and the workpiece must be transferred to an electric machining machine. However, if a rotary tool is used to make the tool perform a 6-axis control motion while performing a swing cutting process, the machining can be performed on one machine. Moreover, accuracy and efficiency can also be improved. If a non-rotating tool is used, the rotary position of the rotary spindle must be controlled, and six-axis control is necessary. When using six-axis control machining, when using non-rotating tools, the cutting speed is equivalent to the feed speed, and high-speed machining is not possible. With the rotary cutter, it can adapt to the processing of the original unprocessable parts and shapes, without conversion work, only cutting. It is possible to complete all the processing at one time with high efficiency. Machining center In addition to milling, it is also equipped with a power rotary table that can be turned. The milling machine is mainly made up of the INTEGREX e800V/5 five-axis horizontal milling center of Japan MAZAK. It is based on the five-axis horizontal machining center, which makes the rotary table add turning function and can be installed under one loading. Car and milling are completely processed for round parts; the NTXI milling compound center of Milanese, Italy, adds a turning spindle to the right end of the vertical machining center. Grinding type The multi-axis of the grinding machine was originally visible only on the centerless grinding machine, and most of them were aimed at the automation of loading and unloading operations. Now, a multi-tasking machine that can complete inner, outer and end grinding on one machine is developed. For example, in Europe, a multi-tasking machine with integrated thread and spline grinding functions has been developed. The representative of this type of compound machine is the MGR vertical grinding and grinding machine of MAGERLE of Switzerland. There are multiple grinding heads and one tool holder on the top of the machine. It can grind and finish the parts. Mori Seiki Co., Ltd. The IGV-3NT grinding head can be used for rotary vertical grinding machines, which can process the inner and outer parts and end faces of the parts under one loading. STUDER's S33 universal CNC grinding machine can realize multi-thread threading and internal and external processing under one loading. Round and end face machining. Composite processing of different types of work Intensive processing types of various different principles, such as cutting and grinding, grinding composite; laser processing to combine post-processing heat treatment, welding, cutting; processing and assembly at the same time. In addition, the unique production-type multi-tasking machine with centralized turning and milling functions, especially the gear processing function; combined with laser processing, has developed a composite machine tool with grinding function and laser quenching function. In Europe, we have also developed intensive composite processing machines such as mechanical milling functions and laser three-dimensional machining functions. The development trend of composite processing technology Composite processing technology is the development direction of future machining. With the continuous development of various fields of society, the requirements for the field of machining are also constantly improving. The "three high" processing of high speed, high precision and high efficiency is the basic requirement for future machining, and the traditional processing concept is It is difficult to meet this requirement. Therefore, the field of machining requires continuous breakthrough of traditional concepts, continuous improvement and improvement of processing technology to meet future requirements, and composite processing technology just meets this requirement. Today's composite processing technology is developed to a compound turning and milling machining center based on an ordinary CNC turning center and machining center. This requires that the machine tool manufacturing industry should develop, manufacture, stabilize and promote high-level machine tools with high efficiency, compounding, stability and low cost suitable for modern processing technology based on the existing technical level.
